pandas判断if df.empty:Data Frame 是否为空
判断dataFrame是否为空
import numpy as npimport pandas as pddf = pd.DataFrame(data=[{"A":"one", "B":"1", "C":"yi"}, {"A":"two", "B":"2", "C":"er"}])if df.empty:print("空的")else:print("非空的")
import numpy as npimport pandas as pddf = pd.DataFrame(data=[{"A":"one", "B":"1", "C":"yi"}, {"A":"two", "B":"2", "C":"er"}])if df.empty == False:# 有内容到print("非空的")else:print("空的")
写方法的时候都是try except 那样写，但是还不够，有可能会遇到传过来的df是空的，那么就要使用这种方法
